This test uses sensors to quantify the pressure between two objects coming into contact. Pressure mapping has many widespread applications. In assistive technology it is commonly used by clinicians to determine the suitability of a wheelchair cushion and by researchers to investigate support surfaces, risk factors for ulceration and ulcer prevention protocols.
Pressure mapping systems can be made in many configurations for different uses; thin mats used by seating specialists are the most common clinical use. These mats are approximately 18” by 18” and composed of a matrix of small sensors and a cover that read pressure at individual locations on the thigh or buttock. This data is transferred to a computer for analysis. Evenly distributed pressure is preferred.
